[Bug middle-end/24853] New: scheduling takes 40% or more time

[bonzini at gcc dot gnu dot org]

For current mainline and Apple 3.3/4.0, the top pass in the profile is

 scheduling            :  14.99 (42%) usr   4.32 (75%) sys  19.32 (46%) wall

Note that at -O0, instead, it is

 global alloc          :   1.06 (30%) usr   0.03 ( 5%) sys   1.09 (26%) wall

but I doubt we can do much about it.
